If one tries to insert a glyph via drag'n'drop from glyph palette (Insert > Glyph) the palette itself is greyed out, and the respective text frame in editing mode cannot be selected on canvas. One has to create another item or use the Document Outline to enable the selection of the text frame again.

Steps To Reproduce

1) Create text frame

2) Double-click into the frame to enable editing

3) Open the Insert > Glyph dialog and expand it to see the glyph table

4) Drag a glyph with the mouse into the text frame.

Additional Information

I'm aware of the fact that this is not how it's supposed to work (although maybe it should?). What's important in this case is that 1.4.x rightfully ignores the attempted operation, whereas in 1.5.0svn it causes a problem.
